One Arm Forward Triceps Extension With Resistance Bands

Isolate and overload one tricep at a time using band resistance for clean elbow extension strength.

Primarily trains: Develops the triceps brachii through resisted elbow extension in the horizontal plane, emphasising the long and lateral heads.

One Arm Forward Triceps Extension With Resistance Bands — demonstration

Step-by-step demonstration

Sets & reps

3 sets × 12–15 reps per arm, 45–60 s rest between sets; this rep range and continuous band tension targets hypertrophy and muscular endurance, making it well-suited for beginners building tricep size and elbow-extension control.

Tempo

2-1-1 — a 2-second eccentric return builds time under tension in the tricep without requiring heavy load.

Breathing

Inhale at the start position (elbow bent), exhale forcefully as you extend the arm forward.

Step 1 of 2

Setup

Get into position before the first rep.

1Anchor the resistance band to a door anchor or fixed point at chest height behind you.
2Attach a handle to the end of the band, or grip the looped end firmly.
3Stand facing away from the anchor, approximately 60–90 cm away — far enough to feel tension in the band at the start position.
4Stagger your feet (opposite foot forward to your working arm) for a stable base.
5Raise your working arm so the upper arm is parallel to the floor, elbow bent at roughly 90°; support the underside of your working elbow lightly with your free hand to keep it locked in position.

Step 2 of 2

Execution

The actual movement, one rep.

1Brace your core and fix your upper arm parallel to the floor — it must not drop or rise during the rep.
2Exhale and extend your elbow, pressing the handle forward until your arm is fully straightened.
3Hold the fully extended position for one count, squeezing the tricep.
4Inhale and slowly return the handle back toward your ear under control, maintaining upper arm position.
5Complete all reps on one side before switching arms.

Form cues

What a good coach would say in your ear.

Lock the upper arm — only the forearm moves.
Keep your wrist neutral; don't let it flex or hyperextend under band tension.
Squeeze at full extension before you reverse.
Stagger your stance wide enough to feel stable — don't let the band pull you backward.
Chin tucked, ribs down — avoid arching your lower back to compensate.

Avoid these

Common mistakes.

The technique errors that quietly undo your training.

Dropping the upper arm during extension: this recruits the shoulder and removes load from the tricep — the upper arm must stay parallel to the floor throughout.
Using a band that's too light and swinging through the rep: momentum bypasses tricep tension; choose a band that makes the last 2–3 reps challenging with strict form.
Hyperextending the elbow at lockout: snapping the joint through the end range stresses the elbow ligaments — stop just short of full lockout if you feel joint stress.
Rotating the torso to complete the rep: trunk rotation shifts the work to the shoulder and chest; brace your core and keep hips square.
Standing too close to the anchor: a slack band at the start provides no eccentric loading — ensure there is tension throughout the entire range of motion.

Variations & progressions

Make it harder. Make it easier. Make it fit.

Two-arm forward triceps extension with band: both arms extend simultaneously for greater time efficiency.
Overhead band triceps extension: anchor the band low and extend overhead to maximise long-head stretch.
Cable single-arm triceps extension: direct machine equivalent for more precise load control as you progress.
Bodyweight triceps dip (bench): regression-free alternative when no band or anchor is available.

Safety

Avoid this exercise if you have an acute elbow or shoulder injury, as the fixed upper-arm position places sustained stress on the elbow joint. Those with tennis elbow (lateral epicondylitis) should use a very light band and stop if pain increases. Ensure the door anchor or anchor point is secure before each set — a failed anchor under band tension can cause falls. If you feel sharp pain in the elbow joint (not muscle burn) at any point, stop immediately and consult a physiotherapist.
